Sponsor

University of Washington

Enrollment

140 participants

Start Date

Apr 1, 2023

Study Type

INTERVENTIONAL

Conditions

Urinary Stone Urinary Calculi

Summary

This is a prospective, open-label, multi-center study to test the clinical feasibility of facilitating stone passage by the combination of breaking and repositioning stones with ultrasound, without the need for anesthesia.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying a medical device called Burst Wave Lithotripsy (BWL) and Ultrasonic Propulsion (UP) for people with urinary calculi and urinary stone. The study is currently recruiting participants at 3 locations. People eligible for this study include aged 18 Years and older.

This summary was AI-generated to explain the trial in plain language. It is not medical advice. Always discuss eligibility with your doctor before enrolling in a clinical trial.

Interventions

DEVICEBurst Wave Lithotripsy (BWL) and Ultrasonic Propulsion (UP)

Novel ultrasound technologies to facilitate passage of stones.This includes Burst Wave Lithotripsy (BWL), a technology to noninvasively fragment urinary calculi within the kidney and ureter, and ultrasonic propulsion, a technology to non-invasively reposition stones within the kidney and ureter. BWL uses short multi-cycle bursts of low amplitude ultrasound to induce stone fracture. This is in contrast to traditional extracorporeal shock wave lithotripsy (SWL), which employs a brief single compression/tensile cycle of high amplitude (shock) waves to achieve stone fracture. Ultrasonic propulsion uses long multi-cycle bursts of low amplitude ultrasound to move stones within the collecting system.
